Château de Jambville
Highlight • Castle
Perched on the heights of Vexin, Jambville castle is known to house the national training center for scouts and guides in France.
Each year, more than 2,000 executives participate in training. Its architecture is special since it has evolved over the centuries.
The vaulted cellars are from the 13th century, the wing from the Henri IV period and the central pavilion dates from Louis XIV.
The castle park, created in the 18th century, is a vestige of the royal forest of Arthies.
It covers 52 ha of woods and meadows and is made up of very rare tree species such as Himalayan cedar.
Also note the presence of a Greek temple built in 1775 and an old icehouse where blocks of ice taken from the frozen Seine were stored in winter. Today it is used as an oratory.
The castle can accommodate groups, associations, companies for stays, seminars during the week and at weekends. Services are also offered such as the organization of weddings or family meals.
The park is open to the public all year round.

Sainte-Thérèse-de-l'Enfant-Jésus Church of Élisabethville
Highlight • Religious Site
Although it was restored in 1986, it has not been maintained for several years. But its so particular style in reinforced concrete is still worth the detour!

Is it allowed to cross? Not sure... I did, I was looked at and greeted. But not blocked. However, it's not easy to get out on the other side, the exit is closed. It's possible to go through a small door.

This section parallel to the Seine cycle route is not very smooth. The large number of holes are filled with ballast (large stones) from the SNCF tracks. Without suspension it hurts :D

This gas-fired Edf power station has been closed for several years; however, these two immense chimneys, which I hope will remain as a testimony to a certain era, have the major interest of being visible from dozens of kilometers around and are for me an excellent landmark to locate myself during my bike rides.

The Porcheville thermal power plant is a former power plant, its final shutdown having taken place on May 1, 2017. It is located in Porcheville in the Yvelines (France) on the banks of the Seine, about fifty kilometers northwest of Paris. It was operated by EDF. The two chimneys of the plant are 220 meters high to evacuate their fumes well above the 70 m cliff facing the site on the left bank of the Seine.
